2012 Volkswagen Jetta TDI ProblemsCheck Engine Light Due to Issues With Glow Plugs/Wiring Harness
Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.
Rear door drivers-side. When using Keyless entry doors won't lock. The door above is culprit. All others lock. A short alarm sounds when all doors are locked. Presently no alarm sounds. Any suggestions for a fix. By the way I did use my second clicker which is brand new. Therefore battery is new.
Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.

2012 Volkswagen Jetta TDI RecallsPotential Diesel Fuel Leak
On the 2.0L TDI common rail Diesel engine/clean Diesel engine, fuel injection pulses could coincide with the natural frequency of injector line #2. This resonance creates additional stress on the fuel line. Small cracks could develop in the #2 injector line, resulting in a Diesel fuel leak. A fuel leak always increases the risk of a fire. Dealers will install an improved #2 fuel injector line and install vibration dampers on all of the injector lines to correct this concern. The Volkswagen/Audi recall number is 23J9/V5.
